structured_description error-- Too many subattributes for attribute: structured_description

Hello.

I have followed the instructions to prepend the trained_algorithmic_media: at the start of structured_description field. I have a sample below:

structured_description

I get this error for every item I am adding to my supplemental feed. Some include colons and quotes inside the descriptions but I've wrapped in quote as suggested here: https://support.google.com/merchants/answer/6324468?hl=en&ref_topic=6324338&sjid=5739341581511964907-NC

Any ideas what could be causing this.

I narrowed it down to instances where there are both double quotes and colons in the structured_description. It appears their recommendations of wrapping in double quote for colons and adding an addition double quote for quotes only works in either scenario, but not both. I replaced with an em-dash and everything worked as intended.

Yes, MC support mentions adding those quotes, etc. but you will notice that we did not include these recommendations in the FeedGen README; you really only need to add the trained_algorithmic_media: prefix. That's it.

This is because Google Sheets automatically adds quotes to cells containing text content, and escapes it as well, so there's no need for you to "manually" do it.
